I wonder if adding bulbs to the brake light circuit might damage the cruise control. I recall reading a warning in a catalog somewhere about this or a similar issue.
Also, tell me about these 12V 1 watt LED "bulbs;" are they available with an OEM style socket? I'd be tempted to upgrade to these as my tail-lamps burn out. (Except for the brake lights; I'd want a knowledgeable tech to give the ok for that change.) I imagine that an LED would have a much, much longer life than a tungsten incandescent bulb.
